TouchDetection
= Specifies the value to which the TouchDetection SFP-II
global parameter is to be set. The TouchDetection global
parameter enables or disables the touch system hardware
that detects touches. For example, disabling touch
detection on an IR touch system would cause the touch
system to stop scanning the IR beams to detect touches.
Legal values for the touch detection parameter are:
00 = Touch detection disabled
01 = Touch detection enabled
Note that the TouchDetection SFP-II global parameter is
a shared parameter and corresponds to the Touch
Scanning SFP global parameter. As with all shared
parameters, there is no SFP-II default for this parameter.
The initial value of this parameter is equivalent to the
value of the corresponding SFP parameter at the time
that the touch system is switched to the SFP-II protocol.
Refer to Chapter 5 for more details on shared parameters.
TouchStateReportType
= Selects the type of touch state report that is to be sent
when the touch system detects a change in the touch
state. Legal values for the touch state report type
parameter are:
01 = Touch State Report (default)
02 = Multi Touch State Report
03 = Raw Touch State Report
Note that the values for the touch state report type
parameter match the function numbers for the various
types of touch state reports. For example, the value of 03
for the Raw Touch State Report matches the function
number of 03 for the GetRawTouchState function.
TouchReportingMode
= Determines under what conditions TouchState reports
should be sent. Legal values for the touch reporting mode
parameter are:
